Hi, kptmatch.count() returns the number of matching keypoints pairs. while kptmatch.match() returns a list of tuples of matching keypoints indices. So they should be the same length, if count() returns 5 (5 pairs match), match() should return a list of 5 tuples [(0, 1), (1, 2), etc...]

This features was requested by someone and was never actually tested, I fixed now. Are you doing something with it ? would you like a patched fw image ?

Yes, Ibrahim can get you an updated M4 firmware. We have to disable the FLIR driver though to do this which requires me to get invloved in the firmware. We are a little busy right now with Maker Faire so it will be a while.
